China unveils ambitious space projects, to probe black holes, search for aliens...

BEIJING, Aug. 21 (Xinhua) -- China will launch several space projects, including a hard X-ray telescope for black hole studies, between 2014 and 2016, according to a senior Chinese astronomer.

Su Dingqiang, an academic at the Chinese Academy of Sciences and former president of the Chinese Astronomical Society, revealed some details regarding the hard x-ray modulation telescope (HXMT), China's first space telescope, on Tuesday at the opening ceremony of the International Astronomical Union (IAU)'s 28th General Assembly.

The hard X-ray band is a key waveband for high-energy astrophysics studies. Hard X-rays originate mostly from regions close to black holes and have high penetrative power, making them important tools for studying physical processes in extreme conditions, such as high matter density and high energy density.

Su said China will develop another satellite, the dark matter particle explorer (DAMPE), to help detect high-energy electrons and gamma rays, as well as a telescope to study the solar magnetic field and a Sino-French joint mission to study gamma ray bursts.

Su said Chinese scientists are also planning to establish an Antarctic astronomical observatory.

Cui Xiangqun, an academic at the Chinese Academy of Sciences and president of the Chinese Astronomical Society, said a lot of work has been done to gain experience for the future construction of an observatory in the Antarctic.

An Antarctic Survey Telescope (AST) was installed there at the beginning of the year and another AST will be installed in 2013, said Cui. China's first Antarctic telescope was installed in 2009.

"We can only send scientists there once a year and each time they can stay no more than three weeks. These telescopes help us detect problems via remote control," Cui said.

"Some of the technological problems we face there are similar to those in space, like low temperatures," Cui said.

However, Cui was optimistic about the Antarctic facility. "It has drier air, better visibility and fewer background disturbances. Its turbulent boundary layer is closer to the ground compared to other sites on the ice slope," she said while describing the area near the telescope.

Chinese space exploration has developed rapidly in the past decade. Some large-scale astronomical projects in China, including the Large Sky Multi-Object Fiber Spectroscopic Telescope (LAMOST) completed in 2008 and the Five-hundred-meter Aperture Spherical Radio Telescope (FAST) to be completed in 2016, have drawn global attention.

The ongoing conference, the first of its size to be held in China, is itself a historic occasion for the country.

"China's technology has advanced markedly, and some of its buildings are really world-class. The fact that we are meeting here is an indication that China has emerged in a short period of time to be competitive on the world stage in the science of astronomy," said Robert Williams, IAU president.

China to probe black holes, search for aliens

Look out space, the Chinese are coming...
China will ramp up its space exploration plans from 2014, with shiny new kit to probe black holes, study dark matter and search for signs of alien life, according to one of the country’s top astro-boffins.

Su Dingqiang, former president of the Chinese Astronomical Society and member of the Chinese Academy of Sciences, revealed the plans to local media at the opening ceremony of the International Astronomical Union (IAU)'s 28th General Assembly on Tuesday.

He said that a hard x-ray modulation telescope (HXMT), currently under construction, will be sent into orbit around the Earth between 2014 and 2016 using a Ziyuan II satellite, according to Xinhua.
The HXMT project web site has the following on the telescope:
Hard X-ray band is a key waveband for high energy astrophysics study. Exploring various kinds of black holes is a major frontier of physics and astronomy in the new century. Hard X-rays originate mostly from regions closest to black holes and are highly penetrative, and are therefore important tools for studying the physical processes in the extreme conditions such as high matter density, high energy density, high electric-magnetic field, and high gravitational field.
Also planned is a dark matter particle explorer (DAMPE), expected to be launched by 2015, as well as a telescope to study the solar magnetic field and a joint project with France to study gamma ray bursts, the report said.

Always striving to be the biggest and best on Earth, China is also set to complete the world’s largest radio telescope in 2016.

The 500-metre aperture single dish giant is being built in in Guizhou province, southern China, at a cost of over 700 million yuan (£69.3m).

It’s designed to be three times more sensitive than the current world record holder, meaning that it should be able to see further into space than ever before.

For the record, it will supplant the Arecibo Observatory in Puerto Rico – known to Bond fans as the setting for the climax of Brosnan flick Goldeneye – as the world’s largest and most sensitive single aperture telescope. ®
